FURMAN D. SPEAR, OF BROOKLYN, NEW YORK, ASSIGNOR TO ARM- SPEARMANUFACTURING COMPANY, OF NEW YORK, N. Y.

SIGNAL-LAM P.

Patented March 27, 1906.

Application filed November 8,1904. Serial No. 231,834.

To all whom it may concern:

Be it known that I, FURMAN D. SPEAR, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Signal-Lamps, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

My invention relates especially to that class of signal-lamps the bodywhereof has one or more light-openings and wherein colored glasses areprovided for interposing between the flame of the lamp and alight-opening when it is desired to change the signal given, and has forits object the provision of simple and effective means for manipulatingsuch colored glasses from the exterior of the lamp-body and without thenecessity of opening any part of the body to reach. the interior toefiect the change.

To attain the desired end, my invention consists, essentially, in a lampin which is comprised a lamp-body provided with one or morelight-openings, one or more colored glasses mounted within thelamp-body, and means for moving said glasses over the lampburner to orfrom the light-openings, all of which will be hereinafter first fullydescribed and then pointed out in the claims.

In the accompanying drawings, forming a part hereof, Figure 1 is avertical central sectional view of a lamp embodying my invention at linea a of Fig. 3, and Fig. 2 is a like view at line b of the same figure.Fig. 3 is a horizontal sectional view at line 6 e of Fig. 1. Fig. 4 is avertical sectional view at line c of Fig. 3, and Fig. 5 is a like viewat line (Z d of the same figure. Fig. 6 is a horizontal sectional viewof a lamp wherein two movable colored glasses are employed, and Fig. 7is a like view of a lamp wherein each colored glass may be separatelymanipulated.

Similar numerals of reference wherever they occur indicate correspondingparts in all the figures.

1 is the body of the lamp, made of any suitable material.

2 represents light-openings. In the present instance the said openingsare shown as provided with lenses; but plain glass or the equivalent maybe substituted therefor, if desired.

3 is a holder for spare colored glasses 4 and 10.

5 is a supporting-bracket.

7 is an oil-pot provided with a burner 8.

9 represents frames for carrying the larger size of glasses 4, which maybe of any color designed for giving the requisite signal. Two frames 9are connected together at 11, (see Fig. 3,) one frame being secured to asleeve 12, forming a shaft which passes through the lamp-body andprovided with a manipulating knob or button 13. The other frame 9 ispivoted on a finger 14, fixed to the lampbody. A second set of glasses10 is carried by frames 15, connected together at 16.

17 is a shaft fixed to one of the frames 15, said shaft passing throughthe sleeve or hollow shaft 12 and being provided with a button 18 or theequivalent. The otherframe 15 is pivoted on the finger 14.

19 and are fingers on which the frames rest, supporting the glasses in aproper position.

Referring to Fig. 3 of the drawings, the smaller set of glasses in theframes 15 is shown as in position between the lamp-burner and the lensesor openings 2, and the color of the light transmitted will be obtainedthrough the medium of such glasses, one of which may be green and theother red. If it is desired to show White light only, the turning of theshaft 17 by means of the button 18 will throw the glasses over the topof the burner, and the frames will rest on the finger 19 in front of theother frames 9. The glasses in the frames 9 are green and revolved overthe burner by means of the button 13 to or from the light-openings 2.

In the lamp illustrated by Fig. 6 of the drawings the light openings areprovided with white lenses, and the movable glasses within the lamp-bodyare green. They may be carried by connected frames, or the frames may bedisconnected, in which case separate manipulating-shafts are required.

In the lamp illustrated by Fig. 7 of the drawings each glass isseparately mounted and provided with a manipulating shaft and button.

It will thus be seen that I have provided a very simple means ofproducing the light or combination of different-colored lights requiredfor signaling, the same being devoid of complicated mechanism andwithout the necessity of changing the glasses by hand. By

revolving the glasses over the burner it is not necessary to provide anyextension or enlarge the lamp-body in order to accommodate the parts forholding the colored glasses I have added to the ordinary signal-lamp.

Having now fully described my invention, what I claim as new therein,and desire to secure by Letters Patent, is

1. A lamp-body having light-openings, in combination with one or morecolored glasses within the lampbody, carried by a horizontally-revolubleshaft, the axis of rotation being oblique to the axes of thelightopenings.

2. A lamp-body having light-openings, in combination with a plurality ofcolored glasses within the lamp-body, carried by ahorizontally-revoluble shaft, the axis of rotation being oblique to theaxes of the light openings.

3. A lamp-body having li htopenings, in combination with a pluraIity ofcolored glasses within the lamp-body, carried by ahorizontally-revoluble shaft, the axis of rotation being oblique to theaxes of the lightopenings, and means for manipulating the shaft from theexterior of the lamp-body.

4. A lamp-body having light-openings, in combination with a plurality ofsets of colored glasses mounted on independent, horizontally-revolubleshafts within the lampbody, the axes of rotation being oblique to theaxes of the light-openings.

5. A lamp-body having light-openings, in combination with a plurality ofsets of colored glasses mounted within the lamp-body on independent,horizontally-revoluble shafts, the axes of rotation being oblique to theaxes of the light-openings, and means for manipulating said shafts fromthe exterior of the lamp-body.

6. The combination with a lamp-body provided with a light-opening, of acolored glass mounted within the lamp-body, and means for rotatablymoving said glass over the plane of the lamp-burner, across the interiorof the lamp-body, to or from the opening.

7. The combination With a lamp-body pro vided with a plurality oflight-openings, of a plurality of glasses mounted within the lampbody,and means for rotatably moving said "glasses over the plane of thelamp-burner,

across the interior of the lamp-body, to or from the lenses or openings.

8. The combination with. a lamp-body provided with a plurality oflight-openings, of a plurality of sets of glasses mounted within thelamp-body, and means for independently rotatably moving either of saidsets of glasses over the plane of the lamp-burner, across the interiorof the lamp -body, to or from the lenses or openings.

In testimony whereof I hereto ailix my signature in presence of twowitnesses.
